GAS-SSTOVE.

SPECIFICATION forming part of Letters Patent No. 427,129, dated May 6,1890.

Application filed May 20, 1889. Serial No. 311,460. (No model.)

T0 aZZ whom it may concern:

l $e 1t known that I, SAMUEL STEWART, a citizen of the United States,residing at Newark, Essex county, New Jersey, have invented certain newandusefulImprovements in Gas- Stoves, fully described and represented inthe following specification and the accompanying drawings, forming apart of the same.

The object of this invention is 'to furnish by a cheap and efficientconstruction a gas stove in which the burners are Wholly exposed to thesurrounding atmosphere and are thus adapted to radiate freely, while theamount of metal in contact with the body of the burners is madeexceedingly small, so as to absorb and radiate as little heat aspossible. The entire apparatus is thus adapted t2) 1use where theradiated heat is objectiona e.

The invention also consists in a particular construction for the burnerswhereby the flame may be brought into closer contact with the top of thestove and with the articles resting thereon when required.

In the drawings, Figure 1 is a side elevation of the stove; Fig. 2, aplan of the same. Fig. 3 is a sectional plan of the burner-grat- 1ng online y y in Fig. 1; Fig. 4, a section of the same on line xx in Fig. 3;and Figs. 5 and 6, avertical section, upon a larger scale, of one of theburners in two different positions.

a is the top of the stove. provided with holes b, over which thearticles to be heated are set.

(Z are legs extended from the corners of the top, and e is a gratingaffixed between the legs below the top to support the burners f and thefeeding-pipe g.

The gratings, as shown in Figs. 2 and 3, are formed as a skeletoncasting of light bars connected to rings e", through which the burnersare inserted. A similar grating e is affixed to the legs, of a higherlevel, with the upper parts of the burners passed through the rings 6,which are thus steadied thereby.

The pipe g is shown provided with branches Z extended transverselybeneath each of the burners and affixed to the grating c by ears '6,each branch being provided with a cock j to shut the gas from eachburner separately. The pipe supports the weight of the burner,

which consists in a bottom thimble if, having the sleeve f fitted toslide upon the same and provided at the top with netting f.

The thinlble t, as shown inFig. 5, is provided with holest atitsopposite sides, through which the pipe Zis inserted, as shown in Fig. 6.The sleeve f is provided with slots f at the bottom upon opposite sides,as shown in Figs. 5 and 6, and is thus adapted to set down over the pipe1, as indicated in the two burners at the left side of Fig. 1. Thesleeve is also adapted to be lifted to bring the netting f closer to thetop a, as shown at the right side of Fig. 1, and as the flame is locatedupon the netting by the mingling of the air and gas beneath the samesuch elevation of the sleeve obviously brings the flame closer to thearticles placed upon the stove-top. The sleeve may be sustained byfriction upon the thimble t when thus lifted, or it may be turned atright angles to its lowest position, as shown in Figs. 5 and 6, and thelower end of the sleeve may thus rest upon the pipe to hold itpositively at such elevation. By turning the sleeve until the slots fallover the pipe the sleeve may be lowered, as shown at the left side ofFig. 1.

It will be seen that the gratings e a contain very little metal and arethus not adapted to absorb and radiate heat, while the interspaces 5between the different bars of the grating permit a very free circulationof air around the gratings and burners and thus operate to rapidlydiffuse the heat and prevent any portion of the stove from acquiring ahigh temperature.

The stove is thus adapted for use in apartments where radiated heat isobjectionable, While the adj ustability of the burnersleeves f enablesthe operator to adjust the flame to or from the article to be heated,and to thus economize the consumption of the gas and the utilization ofthe heat in the most effective manner.

It will also be seen that the burners are exceedingly simple and cheap,consisting merely in the open-bottom tubes into which the air entersfreely to mingle with the gas which escapes from one or more apertures Zformed in the pipes Z within the thimble t.

The nettings f are commonly used for such gas-burners; but any form ofperforated metal or suitable material may be employed in practicing myinvention.

I am aware that it is notnew to construct a lamp-stove with a burnersupported by means of the supply-pipe therefor, as in United StatesPatent No. 329,598, dated November 3, 1885, and that it is not new toprovide a casing inclosing the burner to serve as an air-guide to directthe heated air against the bottom of the vessel to be heated, suchcasing having an adjustable sleeve at its upper end, as in United StatesPatent No. 248,611, dated October 25, 1881, and No. 254,052, datedFebruary 21, 1882. I hereby disclaim theabove patents, limiting myselfto the specific construction claimed herein.

7 Having thus set forth myinvention, What I claim herein is 1. Thegas-stove consisting in the top a, legs cl, and skeleton gratings e. esustained between the legs at different heights, with rings 6' to admittubular burners, pipes Z, fixed beneath the grating e transverse to therings, thimbles t, afiixed upon the pipes, as described, and the sleevesf, provided with nettings f, and movable vertically upon the thimblesfor adjusting the flame to and from the top of the stove Withoutaffecting its size, substantially as shown and described.

2. The gas-stove consisting in the top a, legs d, and skeleton gratings6 e sustained between the legs at dilferent heights, with rings 6' toadmit tubular burners, pipes Z, fixed beneath the grating e transverseto the rings, thimbles t, atfixed upon the pipes, as described, and themovable sleeves f, provided with opposite slots f in their lower ends,and provided with netting f, and adj ustable vertically upon thesleeves, substantially as herein set forth.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

SAMUEL STEWART.
